I need to use multiple versions of JAVA on one computer. I need to use JAVA 1.6.0_10 and JAVA 1.6.0_23. How do I place both versions on one computer.
On older computer I can have both versions show. But on newer computer only one version shows.
I recommend the following for your reading pleasure:

How to get more than 256 bytes data
hello.
I use Schlumberger 32K Card�iJava Card 2.1�j.
Please tell me how to get more than 256 bytes data from the applet in the card!!
According to JCRE specification, need to use Get Response Command.
What is Get Response command?
Do I have to write processing of Get Response command to an applet?
Or JCRE processes Get Response command?
If knows, please tell me about!!
Thanks.Thanks for your response!!
I understand that I have to write processing of Get Response command to an applet.
But case of Schlumberger 32K card, when host send Get Response command to an applet, card reply 6F-00!?
I'm investigating now, and it seems that response is returned before applet processes Get Response command(CLA = 00, INS = C0).
Do JCRE perform the process of Get Response command? -
Need a little help with JAR creation
I've created a JAVA program with the Forte IDE and now I want to make it executable without the IDE. I read on this forum that all I had to do was create a JAR file, so I tried but I get an error (see below). Could someone point out my error please.
Directory Tree:
vio082\vio\app\
DOS command to create executable JAR:
"java -jar cmf trackerManifest.txt trackerTest.jar trackerTest.Class"
ERROR I RECEIVED:
"Exception in thread "main" java.util.zip.ZipException: The system cannot find the file specified
at java.util.zip.ZipFile.open<Native Method>
at java.util.zip.ZipFile.<init><Unknown Source>
at java.util.zip.ZipFile.<init><Unknown Source>
at java.util.zip.ZipFile.<init><Unknown Source>"
This was my file trackerManifest.txt:
Main Class: trackerTest
[cr]
This is the begining of my file trackerTest.Class:
package vio.app;
import javax.comm.*;
import vio.tracker.*;
import java.net.*;
import java.io.*;
public class trackerTest {
public static void main (String argv[]) {Thanks for the help so far. My first problem was that the directory with the "jar" command was not in my path (now that fixed). My application still won't execute and I think it has to do with the following:
My application uses the serial port to communicate with a device and uses a socket server to communicate with a C++ program. The following JAVA utilities are imported to make my application work:
javax.comm.
java.net.
ijava.io.
If I use the command:
"jar cvfm trackerTest.jar trackerManifest.txt trackerTest.Class"
will the appropriate files from javax.comm, java.net and ijava.io also be incorporated into the jar file? If not, how are they made available when I distribute my jar to other users?
Second question:
Should I be using:
"jar cvfm trackerTest.jar trackerManifest.txt vio082/*.*"
to capture all the other classes required by my package that are in other directories above and below the trackerTest.class directory?
Any help is greatly appreciated.

i have placed the files in my root directory on IIS, can anyone help, IJava-Queries Post
hi!
i guess u r using the servlet engine(ServletRunner) that comes along with jsdk. what's ur version? what u do is, set the classpath to where ever u have the jsdk directory, if u dont use any IDE, type this in the dos prompt, (for eg, ur jsdk is in local c drive)
c:\ set classpath=c:\jsdk4.0\lib;
then compile the file, if u use an IDE, what's that u r using?
>>>
The problem here is that the OP does not know that a web server is needed to run JSP or is it a Typo

If you can do it with C++ why not doing it in Java?
C++ is a great language but I dream of doing flex development
with java instead of actionScript simply because it is a superior
language (than actionScript). The bad side would be that it would
kill the JavaFX project.
I feel actionScript is oriented toward graphists and animator
and miss some business/serious features like generics, abstraction,
comprehensive collection library and thread synchronization.
C++ does have all of these. I don't what to enter a C++
versus Java flame war but I just would like to point out that there
is a need for a Flash VM that runs Java classes.quote:

Hi Marcus,

I will be very thankful if you could please tell me how you
solve this error.

Node/NodeList problem [XML/DOM]
Problem: IJava code is not printing out the 2nd node but rather printing the 1st one twice from the XML file.
Node firstChildren = doc.getFirstChild();
String nodeName1 = firstChildren.getNodeName();
System.out.println(nodeName1);
Node nextNode = firstChildren.getNextSibling();
String nodeName = nextNode.getNodeName();
System.out.println(nodeName);the XML looks like this:
<Office>
<Employee Employeename="Ryan">
<Position>Claims</Position>
</Employee>
</Office>The Java code prints out:
Office
Office
Also is there a way/method to get the values of an element without making the element values into attributes? getNodeValues returns null for elements.Not sure your question, You should only have one node at the root of the tree, so you shouldn't be getting two different nodes. walking the roots 'siblings'
An element doesn't have a 'value'. What we perceive a an elements value is just child nodes (Text, Elements, etc) that you need to walk with getFirstChild, getNextSibling, etc.
